Distorted Sun at sunset. A distorted solar disc at sunset,with a mirage forming below it. A mirage is an atmospheric phenomenon caused by the differential heating of layers of air. As air warms up,it expands,and this affects its refractive index. Light rays slanting down from a cool layer of air to a hot layer,such as one in contact with hot ground,will be refracted to a shallower angle. If the angle is sufficiently shallow,the light rays are refracted so that they appear to be reflected upwards | |
